"Its dark matter particle detection payload consists of four sub-detectors and payload tubes, including plastic scintillation array detector PSD, silicon array detector STK, BGO calorimeter, and neutron detector NUD."

"I can provide all these related technologies."

"but......"

After a pause, he continued: "However, the technology used on the Wukong detection satellite is probably difficult, or theoretically impossible, to be applied to the Large Strong Particle Collider."

"Because they're not the same thing at all."

Hearing this, Xu Chuan nodded slightly disappointedly and said: "If this is the case, then there is really nothing we can do."

These days, he has been reading CERN-related information and learned a lot about detection technologies.

Generally speaking, technologies for detecting dark matter can be divided into three major categories.

The first type is direct detection, that is, detecting the collision process of dark matter particles with ordinary matter when passing through the earth. Research in this area is currently mainly carried out in the Jinpingshan Underground Laboratory in Sichuandu.

The other type of second category is indirect detection, that is, looking for photons, positron and negative electron pairs, positive and negative protons, positive and negative neutrinos, etc. produced by the annihilation or decay of dark matter particles. This type of research is carried out by Wukong.

The last category is collider and accelerator detection.

In China, Chang Jin can be said to be the top expert in this field. Even in the world, the Wukong satellite is the space detector with the widest observation energy range and the best energy resolution.

He all said that this road is basically unworkable and the development direction is completely different, so it is unlikely that the collider will apply this technology.

Chang Jin nodded and continued: "The principles, methods and technologies used by accelerators and collider to detect dark matter are completely different from indirect detection methods, including the particles we are looking for."

"So if we hope to use the technology used on Wukong to transform the collider's detector, it may be difficult to do so."

Hearing this, Xu Chuan thought for a while and then asked: "Does Academician Chang have any suggestions or directions regarding detection technology?"

He is just a physicist and is not involved in various particle detection techniques and scientific experimental research.

If he is asked to find the corresponding particle from a series of detected data, he has countless ways.

But designing and manufacturing technology and equipment for detecting particles is not his field of research.

Of course, what he is studying now is not actually detection technology, but the lowest level scientific principles.

Only by finding the core principle can it be possible to create your own detector.

Chang Jin thought for a while and said: "For indirect detection of dark matter particles, the most ideal research object is antimatter cosmic rays."

"Because theoretically, the annihilation or decay of dark matter usually produces equal amounts of positive and antiparticles. In the universe, stars, pulsars, and supernova explosions will produce a large number of such particles."

"So it has the best fit."

"As for the Large Strong Particle Collider, a few years ago, I went to CERN to communicate. At the meeting, someone proposed that the detector should mainly search for the energy and momentum loss signals generated during the annihilation decay of dark matter."

"Maybe the direction of the detector can try this."

"However, whether it is the Wukong satellite or the collider, these are indirect evidence for the detection of dark matter and dark energy."

"If we want to directly observe dark matter, maybe Academician Xu can go to Jinping Mountain."

"Maybe the high-purity germanium detector over there can be applied to the collider?"
